Product Introduction. The series of products are made of mported speciai use slai and high reliable electric energy measure ment (hat is real reactive) Whether the threephase voltageand current of the electric network is balance,Energy accuray. Before deliver, en ationand aging tests.so the quality are reliable. In addition, these products are conformed to GB/T17218-1998 Standard and village users and power departments with three-phase electricity .2. Function and Features. Measure three-phase active energy,do not need calibrate for long-term operation. Three-phase power supply,the energy meter can work normally once any one or two phases are broken. Wide service temperature range; Assuming function of defect phase indication or voltage indication. Way of display:Register、LCD、digital tube; Remote interruption of power supply function.3、Main Technical Data.
